Ho to get gray area where data is missing in source.

[thomasnilsen]

Hello.

How can i get the graph to show a grayish area i gaps where there have been no data from the source. Eg: if the router has been down or out of reach and no data is avalible for a time period. I think i remember seeing this somewhere, but cant figure out how to create it.

Btw: have a few nice and usefull graphs/datasources for Cisco AS5400 access gateways if someone is interessted.

i searched on the forums for blank graphs because that is my problem but i found your post and i know that it is possible to have gray area in your graph because ive seen it too. can you tell me why my graphs are not showing up at all i am running version 0.8.6d on Centos 4.3 and i think the only problem i have is not seeing the graphsat all. thanks alot

RRDTool installed and cacti pointing to it correctly ?
If you run php -f poller.php or php -f cmd.php do you see any error messages?

I use a CDEF function called "Unknown-Data":

Code: Select all

cdef=CURRENT_DATA_SOURCE,UN,INF,UNKN,IF

Just add this at the end of our Graph templates as CDEF Function and use

Graph Template Items with a grey area (Graph Item Type) for example.

Is it possible to keep graphing previous value when it is unknown (like MRTG)? I know this is unsafe because it draws flat graphs even when the source is unreachable but i don't like gaps on my graphs :)
